The present invention relates to a battery pack device for managing discharge balance, in a battery pack device, which includes: M battery modules including N battery cells, wherein M >= 1 and N >= 2 are satisfied; and a management module which is connected to at least one power terminal among +/- pack power terminals for charging or discharging a battery pack, checks the state during or after discharging of the battery pack through the pack power terminal, collects a voltage value for each of M*N battery cells from the M battery modules, and uses the voltage values for each of the M*N battery cells collected in the state during and after the discharging of the battery pack, to manage a voltage balance state for each of the M*N battery cells.

    본 발명의 방전 밸런스를 관리하는 배터리팩 장치에 따르면, 배터리팩(Battery Back) 장치에 있어서, N(N≥2)개의 배터리셀(Battery Cell)을 구비한 M(M≥1)개의 배터리모듈(Battery Module)과 배터리팩의 충전이나 방전을 위한 +/- 팩 전원 단자 중 적어도 하나의 전원 단자와 연결되며 상기 팩 전원 단자를 통해 배터리팩의 방전 중 상태 또는 방전 후 상태를 확인하고 상기 M개의 배터리모듈로부터 (M*N)개의 배터리셀 별 전압값을 수집하며 상기 배터리팩의 방전 중 상태 또는 방전 후 상태에서 상기 수집된 (M*N)개의 배터리셀 별 전압값을 이용하여 (M*N)개의 배터리셀 별 전압 밸런스 상태를 관리하는 관리모듈을 포함한다.
